Lero, fakitale ya Jinbin yamaliza kulongedza valavu yayikulu ya chipata cha DN700.valavu ya chipata cha suliceyasinthidwa mosamala ndi ogwira ntchito, ndipo tsopano yadzazidwa bwino ndipo yakonzeka kutumizidwa komwe ikupita.

Ma valve akuluakulu okhala ndi mainchesi awiri ali ndi ubwino wotsatira:

1. Kuthamanga kwamphamvu: Kapangidwe kake ka mainchesi akulu kamalola kuti madzi ambiri adutse, kuchepetsa kukana kwa madzi ndikuwonetsetsa kuti madziwo akuyenda bwino.

2. Kugwira ntchito bwino potseka: Kugwiritsa ntchito zipangizo zotsekera zapamwamba kwambiri kungalepheretse kutulutsa madzi ndikuwonetsetsa kuti dongosololi likugwira ntchito bwino.

3. Yosavuta kugwiritsa ntchito: Nthawi zambiri imayendetsedwa ndi chowongolera chamanja kapena chamagetsi, chomwe chimakhala chosavuta kugwiritsa ntchito ndipo chimatha kutsegula ndi kutseka mwachangu.

4. Yolimba komanso yodalirika: Kapangidwe kake ndi kolimba, kokhoza kupirira kupsinjika kwakukulu ndi mphamvu zogundana, ndipo kali ndi moyo wautali wautumiki.

Valavu yachitsulo yopangidwa ndi ductile iron gate nthawi zambiri imagwiritsidwa ntchito pazochitika zotsatirazi:

1. Uinjiniya wosamalira madzi: M'madamu akuluakulu, m'malo osungira madzi ndi m'malo ena osungira madzi, ma valve akuluakulu a chipata amagwiritsidwa ntchito kuwongolera kulowa ndi kutuluka kwa madzi ndikuwongolera kuchuluka kwa madzi.

2. Kayendetsedwe ka madzi ndi ngalande: M'mapaipi operekera madzi ndi ngalande mumzinda, valavu yolowera madzi yokhala ndi mainchesi akuluakulu ingagwiritsidwe ntchito kuwongolera njira ndi kayendedwe ka madzi, kuonetsetsa kuti madzi ndi ngalande zikuyenda bwino.

3. Makampani opanga mafuta: Mu makina a mapaipi m'mafakitale monga mafuta ndi mankhwala, ma valve a chipata chachikulu amagwiritsidwa ntchito kuwongolera kuyenda kwa madzi ndi mpweya wosiyanasiyana, kupewa kutuluka kwa madzi ndi ngozi.

4. Makampani opanga magetsi: M'malo opangira magetsi, malo osungira magetsi ndi malo ena opangira magetsi, ma valve akuluakulu a chipata amagwiritsidwa ntchito kuwongolera kuyenda kwa madzi monga madzi ozizira ndi nthunzi, kuonetsetsa kuti zipangizo zikugwira ntchito bwino.

5. Kusamalira zinyalala: M'malo oyeretsera zinyalala, valavu yolumikizira chipata chachikulu imagwiritsidwa ntchito kuwongolera kuyenda ndi komwe zinyalala zikuyenda, kuonetsetsa kuti njira yoyeretsera zinyalala ikupita patsogolo bwino.

Chifukwa chake,valavu ya chipata chachikuluMtengo wagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga uinjiniya wosamalira madzi, makina operekera madzi ndi ngalande, mankhwala a petrochemical, makampani opanga magetsi, ndi kukonza zimbudzi chifukwa cha mphamvu yawo yoyenda bwino, magwiridwe antchito abwino otsekera, ntchito yosavuta, kulimba, komanso kudalirika.
